I am just in the midst of a camper conversion and have been struggling to find out if the following is possible.
I have the following items regarding the charging side of things:
- Victron Orion-TR Smart DC-DC isolated 12v 18A
- Victron BlueSmart 12v 15a 3 output mains charger
- Victron SmartSolar MPPT 100/15
All 3 will be connected via a distribution block to the leisure battery bank (2 x 115ah AGM) which i understand is ok to do, but i would also like to charge the car battery via the mains BlueSmart charger while connected to shore power.
Now i could run a ing switch live to the DC-DC charger so it only comes on when driving, but that means running a cable the length of the van which i could do without, and i'd rather not if i don't have to.
So the question is, would it be a problem if the BlueSmart mains charger was charging the leisure batteries and the car battery, which would then switch the DC-DC charger on as it'll see the high voltage?
